A bus bar assembly installed in a frame for fixing a plurality of stacked battery cells is provided. The bus bar assembly may include: a bus bar fixed to the frame; a flexible printed circuit board electrically connected to the bus bar and configured to sense the plurality of battery cells; and a connection terminal having a protrusion formed on one surface of the connection terminal, is the protrusion being configured to pass through the flexible printed circuit board so as to be electrically connected to the flexible printed circuit board, and the connection terminal configured to be electrically connected to the bus bar through the opposite surface of the one surface, the opposite surface being bonded to the bus bar.

Bus bar assembly and frame assembly

Provided is a flexible circuit board installed on a frame to which a bus bar is coupled. The flexible circuit board may include a central portion having a band shape, first connection circuit portions formed at both ends of the central portion and disposed to face each other, second connection circuit portions extending from the first connection circuit portions in parallel with the central portion, and third connection circuit portions extending from the first connection circuit portions and the second connection circuit portions and connected to the bus bar. An overlapped may be formed when each of the second connection circuit portions is folded toward one side of each of the first connection circuit portions.

Flexible circuit board and frame assembly including same

Provided is a frame assembly for fixing a plurality of stacked battery cells. The frame assembly may include: a frame including an upper surface, a first side surface connected to a first end of the upper surface and a second side surface connected to a second end of the upper surface, the frame being configured to enclose the plurality of battery cells; a plurality of first bus bars disposed on the first side surface; a plurality of second bus bars disposed on the second side surface; and a flexible printed circuit board disposed along the upper surface, the first side surface, and the second side surface of the frame, the flexible printed circuit board being configured to sense the plurality of battery cells.
